The Design And Realization Of Daqing Petroleum Institute Campus Video Frequency Supervisory System

The video frequency supervisory system is widely applied in many situations by its audio—visual effect ,convenience, abundant information and rich content. It's a kind of comprehensive system with strong guard ability. And it's a part of the safeguard system. Its composition includes front end equipment, transmission system and central control system.In this design, combining with the engineering project of"Daqing Petroleum Institute Campus Video Frequency Supervisory System", and by the system master design, the detailed design, the construct control and the system debugging ,etc, the campus video frequency supervisory is planned and designed, the construction progress is controlled , the construction quality is supervised, the project is debugged and approved, the system is safeguarded in the succeeding days and the engineers and technicians are trained.According to the development of video supervisory technique and combining with the project reality, the system design plan is proposed. The system is wholly realized by selecting the management way of two levels of respective control, and the master control part of the system front end is planned by selecting the modulus compatible control system. Based on the research of the video frequency transmission and the video recording, the alarm joining and linkage, rapes and lens control, recording memory and transference ,etc, a lot of problems are solved, such as design and realization of system signal transference , alarm joining and linkage, long distance control of rapes and lens, long distance recording , memory and transference ,etc.This design has abundant functions, high security, high stability, good extension and strong usability, etc.
